How long can Trulicity be unrefrigerated?

Up to 14 days at room temperature below 86°F. After 14 days out of the fridge, the pen must be discarded even if it has not been used.

Can Trulicity be put back in the fridge after being at room temperature?

Yes, as long as it has not been frozen, has not exceeded 86°F, and has not been at room temperature for more than 14 days cumulative.

Can you take expired Trulicity?

No. After the printed expiration date the manufacturer no longer guarantees full potency. Use a fresh pen and dispose of the expired one in a sharps container.

What happens if Trulicity freezes?

Discard it. Freezing damages the dulaglutide protein structure, and the damage is not reversible by thawing. A previously frozen pen may look normal but may not deliver a full dose.

How should I store Trulicity at home?

In the original carton, in the refrigerator at 36 to 46°F, away from the cooling element and away from the freezer compartment. Keep it out of reach of children.

Can I take Trulicity on a plane?

Yes. TSA allows prescription injectable medications in carry-on luggage. Pack the pens in carry-on, not checked baggage, because cargo holds can freeze the pens in flight.

How do I dispose of Trulicity pens?

Place used pens immediately in an FDA-cleared sharps container or a heavy-duty puncture-resistant plastic container with a sealed lid. Follow local disposal rules when the container is three-quarters full.

What is the best travel case for Trulicity pens?

Any insulated medication case that keeps the pens between 36 and 86°F without letting them touch ice or frozen gel packs directly. Lilly does not endorse a specific brand. For trips under 14 days at moderate temperatures, no cooling is required.

What is the best sharps container for Trulicity pens?

Any FDA-cleared sharps container sized to fit the pens. Most pharmacies sell 1 to 1.5 quart containers that hold weeks of weekly pens. A sealed heavy plastic household container works as a backup.

Can I store Trulicity in the door of my fridge?

The door is fine and often better than the back wall because it stays farther from the cooling element. Just avoid letting the carton fall against the back of the fridge where freezing risk is highest.

Does Trulicity need to be refrigerated after first use?

Yes, unless you are within the 14 day room temperature window. Refrigeration is the long-term storage condition; room temperature is a 14 day exception for travel and convenience.

Does Trulicity Need Refrigeration?

Summary: Trulicity pens must live in the fridge between 36 and 46 degrees Fahrenheit, and once you take a pen out it stays good for 14 days at room temperature up to 86 degrees as long as you never freeze it.

This content is for informational purposes only and is not medical advice. Always consult a qualified healthcare provider before starting, changing, or stopping any medication.

The short answer: yes. Trulicity must be refrigerated at 36 to 46°F (2 to 8°C) until you are ready to use it. Once a pen leaves the fridge, you can keep it at room temperature up to 86°F (30°C) for 14 days, then it must be discarded ^[1]^[2]. Never freeze it. A frozen pen is a dead pen, even if it looks fine after it thaws.

That is the rule that matters. The rest of this page covers the edge cases, the travel rules, the spoilage signs, and the disposal steps that the FDA label expects you to know.

The core storage rules at a glance

Condition	Temperature	Maximum time
Refrigerator (before and after first use)	36 to 46°F (2 to 8°C)	Until printed expiration date
Room temperature	Up to 86°F (30°C)	14 days, then discard
Freezer	Anything below 36°F	Never. Discard if frozen.
Direct heat or sunlight	Above 86°F	Discard immediately

The 14 day room temperature window is cumulative, not a fresh allowance each time you take the pen out. If a pen sits on the counter for three days, goes back in the fridge for a week, then comes out for another four days, you have used seven of your 14 days ^[3]. Lilly's instructions for use treat the total time above refrigeration as the limit, regardless of how you broke it up.

Why Trulicity needs the fridge in the first place

Trulicity (dulaglutide) is a GLP-1 receptor agonist built on a recombinant Fc fragment fused to a modified GLP-1 peptide. That structure is what gives it the once-weekly half-life. It is also what makes it temperature sensitive. The folded protein has to stay in its native conformation to bind the GLP-1 receptor on pancreatic beta cells. Cold storage slows the kinetics of unfolding and aggregation. Room temperature speeds them up. Heat above 86°F or freezing both wreck the structure outright.

The FDA-approved label allows the 14 day room temperature window because Lilly's stability data show that the protein stays within potency specifications across that window when the temperature stays at or below 86°F ^[1]. Push past either of those limits and you are off label.

Can Trulicity be injected cold?

You can, but you probably will not enjoy it. Cold liquid stings going under the skin, and the sting is sharper with a 5/16 inch needle injecting into subcutaneous fat than it would be with an intramuscular jab. Most patients pull the pen out of the fridge and let it sit on the counter for at least 30 minutes before injecting ^[3]. That brings the solution close to room temperature without violating any storage rule.

Do not microwave it. Do not run it under hot water. Do not put it on a radiator. Any of those can spike the temperature past 86°F in seconds and silently destroy the dose. Counter, 30 minutes, then inject. That is the protocol.

Can Trulicity be put back in the fridge?

Yes, as long as it has not been frozen and has not exceeded the cumulative 14 day room temperature limit. Pens move freely between the fridge and the counter. The clock that counts is total hours above refrigeration, not the number of trips.

If you left a pen on the counter overnight, it is fine. Stick it back in the fridge. Make a note of the hours it spent out so you can track the 14 day total. If you left it in a hot car, in direct sunlight, or anywhere the temperature climbed above 86°F, do not put it back. Throw it out.

Signs of spoilage

Inspect every pen before you inject. The dulaglutide solution should be clear and colorless to slightly yellow ^[1]. Discard the pen if you see any of the following:

Particles or floating debris in the window
Cloudiness or discoloration that goes beyond a faint yellow
A pen that has been frozen, even if it thawed and looks normal
A pen that has been exposed to heat above 86°F
A pen past the printed expiration date on the carton or label
A pen that has been out of the fridge for more than 14 days

A pen that looks visually fine can still be inactive if the protein denatured silently. The rules about freezing and heat exist precisely because the solution does not always show the damage. When in doubt, throw it out and use a fresh pen.

Can you use expired Trulicity?

No. The expiration date printed on the carton and on the pen label is the date Lilly's stability data stop guaranteeing potency ^[1]. After that date, dulaglutide may have degraded enough that your weekly dose is no longer a full 0.75, 1.5, 3, or 4.5 mg of active drug. You could be under-dosing yourself without knowing it, which matters for blood glucose control in type 2 diabetes.

A pen one day past expiration is not a medical emergency, but it is also not what you paid for. Call your pharmacy for a replacement and dispose of the expired pen in a sharps container.

Traveling with Trulicity

The 14 day room temperature allowance is what makes Trulicity travel-friendly. For trips of two weeks or less you do not need a cooler, ice packs, or any special equipment as long as the ambient temperature stays at or below 86°F.

For longer trips, hot climates, or any situation where the pens might exceed 86°F (a parked car in summer, a beach bag, a checked suitcase sitting on tarmac), use an insulated travel case or a small cooler. Lilly does not endorse specific brands, but the rules are simple: keep the pens cool, do not let them touch ice or frozen gel packs directly, and do not let the case freeze the contents ^[3]. Wrap frozen packs in a layer of cloth or use a cooler with a separate compartment for the medication.

Flying with Trulicity

The TSA permits prescription liquid medications in carry-on bags in quantities greater than 3.4 ounces, including injectable medications like Trulicity ^[4]. Pack the pens in your carry-on, not your checked luggage. Cargo holds can drop well below freezing in flight, and a frozen pen is a discarded pen.

Bring the original carton with the pharmacy label so security can verify the prescription if asked. You are not required to declare the medication, but mentioning it at the security checkpoint usually speeds up the screening of any ice packs or coolers you have with you. Ask for visual inspection if you would rather not run the pens through the X-ray machine, though TSA notes that X-ray screening does not damage injectable medications.

If you cross time zones, take your weekly dose on the same day of the week regardless of local time. Trulicity is forgiving of small timing shifts because its half-life is roughly five days. A few hours earlier or later does not move blood glucose meaningfully.

Hotel mini-fridges

Most hotel mini-fridges run colder than a standard household fridge, and some have a freezer compartment that can dip below 32°F. Do not push the pens against the back wall or near the cooling element. Put them in the middle of the fridge or in the door rack where the temperature is more moderate. If the mini-fridge has a freezer section, keep the pens as far from it as physically possible.

How to dispose of Trulicity pens

Used Trulicity pens go in an FDA-cleared sharps container immediately after injection ^[2]. Do not throw them in household trash. Do not recap the needle by hand. Do not flush them.

If you do not have a commercial sharps container, the FDA allows a heavy-duty plastic household container with a tight, puncture-resistant lid as a substitute. An empty laundry detergent bottle or a coffee can with a sealed lid both work. Label the container clearly so no one mistakes it for trash, and keep it out of reach of children and pets.

When the container is about three-quarters full, seal it and follow your local disposal rules. Most US states run drop-off programs at pharmacies, hospitals, or hazardous waste sites. Some areas allow mail-back disposal services. Search "sharps disposal" plus your state to find the rules where you live.

What about unused pens?

If you have unused, unexpired pens you no longer need (for example, you switched medications), do not throw them away or flush them. Take them to a pharmacy drug take-back location. The DEA runs National Prescription Drug Take Back Day events twice a year, and many pharmacies offer year-round take-back through a drop box.

What to do if the cold chain breaks

If a pen spent unknown hours in heat or got accidentally frozen, treat it as discarded. The cost of replacing a pen is small. The cost of a week of inadequate blood glucose control, possibly without realizing it, is not. Call your prescriber if losing the pen leaves you short for your next dose; they can usually authorize an early refill given the documented cold chain failure.

Trulicity dose strengths and storage are independent

The four available strengths (0.75 mg, 1.5 mg, 3 mg, and 4.5 mg per 0.5 mL) all use the same single-dose pen design and the same storage rules ^[1]. Refrigerator temperature, room temperature window, freezing prohibition, and 14 day room temperature limit apply identically across all four. The only difference between the doses is the concentration of dulaglutide in the pre-filled solution. Storage is the same.

The bottom line

Refrigerate Trulicity. Stay between 36 and 46°F. Pull a pen out when you are ready to dose, let it warm on the counter for half an hour, inject it, and put used pens straight into a sharps container. For travel, the 14 day room temperature window covers most trips without any cooling equipment. Never freeze. Never heat. When in doubt about a pen's temperature history, discard it and use a fresh one. The math on a wasted pen is better than the math on a missed week of glycemic control.
